1 John 1:2 New American Standard Bible (NASB)
2 and the life was revealed, and we have seen and testify and proclaim to you the eternal life, which was with the Father and was revealed to us—
John writes the life was manifested. John was an eyewitness of Christ with many others. They walked with Jesus and saw all the miracles. They saw Him suffer and die at Calvary. They saw the risen Christ. The life John writes of here is eternal life. For Jesus came to give life and give it abundantly. For it is in Christ that our lives are made new. That in Him we become brand new creations. In Christ every day is new. Our sins have been forgiven. Our names are written in the Lambs book of life.
John writes they have seen, testify, and proclaim to them eternal life. John’s life was committed to the proclamation of the gospel. When he met Jesus and made the decision to follow him, he had no idea that his life would change forever. John would commit his life to the proclamation of who Jesus Christ is. To know Christ is to know eternal life. To fail to know Jesus is to be lost and without hope. Without Christ a person is simply a lost sheep without a shepherd. But in Christ we are found and are adopted into God’s family.
Jesus was with the Father. He was with the Father from the beginning. Jesus is not created. He knew The Father intimately and in knowing Christ we are able to know the Father intimately. In Christ we are able to draw near to the throne of grace with confidence. Because in Christ we have eternal life, our sins have been dealt with.
John was combating false teaching that had tried to permeate the body of Christ. Claiming that Jesus was not truly God but was merely born human and at His baptism by John the Baptist the Christ had descended upon Him. To attack the deity of who Jesus is, is to attack the foundation of Christian. If Jesus is not God, then anyone who claims to put their faith and hope in Him are without hope. But many things point to the deity of Jesus. His virgin birth, His signs, wonders, and miracles, His death and resurrection. Everything we believe and build our lives upon is built upon the resurrection of Jesus Christ. In Christ death and the grave have been overcome. In Christ we are set free from our sins.
